BE35.30-N-1001-01B

Friction torque of drive pinion bearing

with radial shaft sealing ring

Nm

1,7...3,38

without radial shaft sealing ring

Nm

1,65...3,74

1

Insert tapered roller bearing on pinion side using measuring piece (01) from   adjustment device.

2

Insert tapered roller bearing at flange and clamp using washer (02) and nut (03) from   adjustment device.

3

Determine friction torque using   torque meter (04) and set to specified value.

 Aim for the upper one third of the specified value.

4

  Insert adjustment device (07) with   dial indicator (05) and holder (06) from   adjustment device into rear axle housing and fix in place using bearing brackets.

5

Position measuring pin (1) from   dial indicator (05) onto measuring piece (01) from   adjustment device, turn   adjustment device (07) to determine zero point and   set dial indicator (05) to zero.

6

Turn measuring piece (01) from   adjustment device, until the measuring pin (1) from the   dial indicator (05) of the measuring piece (01) slips out of the   adjustment device.

 The determined dimension corresponds to the thickness of the spacer washer in front of the pinion-side tapered roller bearing on the drive pinion.
